133300 ÷ 13 
The aim is to understand the frequency of 13 in 133300.

Going ahead to step 1:
1 divided by 13 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 13

Moving on to step 2:
If we divide 13 by 13, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 13 from 13 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 13

On to step 3:
When dividing 3 by 13, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 13

Moving on to step 4:
13 can be fit into 33 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 26 from 33 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 13

Step 5:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1025.0
Subtract 65 from 70 to get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 13

Step 6:
50 divided by 13 is 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 10253.0
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 10253.8
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 13, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 10253.84
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
13 goes into 80 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 10253.846
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
If we divide 20 by 13, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 10253.8461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
If we divide 70 by 13, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10253.84615
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
13 goes into 50 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 10253.846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
If we divide 110 by 13, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 10253.8461538
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
60 divided by 13 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 10253.84615384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 10253.84615384 and a remainder of 8e-09.
